Specification of Letters Patent.

Patented May 7, 1907.

Application filed October 13, 1904. Serial No 228,313.

Several mechanisms or attachments for at taming ihis result have been patented and placed on the market, such devices or mecham isms involving the temporary release Olt the 1 key-controlled te t so that the carriage will be rapidly propelled by its spring irom right to left to a limit prescribed by what is called tabulating stop, this movement or the mech- L amsin which causes it being sometimes termed a jump-feed.

It is to this class oi invention that my present invention relates, and the particular ohieet otthis said prove-u means whereby the exact position in which the carriage will be checked by a given stop may be instantly varied by the operator according to the number" of characters comprising, the-group that is to form a line of the column. For instance, when figures are to be written tor statements of account, bills, invoices etc., the numerals in the groups eon1-. usually vary considerably, and as the units must be written in a vertical line, and the tcnslmndreds etc., similarly written, itis desirable for the sake of speed and accuracy that the machine shall have means for enabling the operator to determine at a glance how far the carriage shall jump in order to write the first numeral of the group in the proper place.

Another object of the invention is to provide a mechanism for the purpose stated, comprising a single variable stop adapted to co-act with one or more fixed but adjustable stops when brought to the desired position by the (.iperator;

Other objects, relating to the general simplicity, eflieiency and durability of the mechanism included in this invention, will be more fully apparent hereinafter.

.\ly invention consists in the construction and combinations of parts substantially as hereinafter described and claimed.

in the drawings hereto annexed,

invention is to provide img l l I have l have shown but one such stop in Fig.

illustrated a preferred embodiment, and a modification of my invention, in connection with suliieient of the parts of an t nderwood type-writer to enable it to be readily understoml by those skilled in the art. ut it is to' be understood that my invention is not limited to either the particular adaption or the exact details of the parts illustrated.

Similar reference characters indicate the same or similar parts throughout the several views.

The frame ot the machine is indicated at 2(1), and one oi the rods tor the carriage 2]. is shown at 2;. 33 indicates the teed rack which is carried by and travels with the carriage. 34. indicates one oi" the usual vi brating feed-dogs co-operating with the rut-k 28- to permit the step-bystep movement of the carriage. All or these parts are well known and need noiurther description or illustration.

Referring to Figs 1, 2, 3 and T to lo, a bar 25 having a series ot vertical slots is secured at its ends to the frame ol' the machine and has its upper surface graduated or provided with scale marks to correspond with the slots in the bar and, of course, corresponding with the usual scale (not shown) at the front ot the machine. In one or more of the slots of bar 25 is placed a stop an. the hape of which is best shown in Figs 9 and 1t). 1 3 but it is to beunderstood that as many will be carx stop presently described. The stop is formed with an upwardly extending portion by which it may be grasped when its location is to be changed, and with a notch forming a shoulder that is engaged by a yielding stop- The ends of the bar 27 enretaining bar 27. ter boxes 28 and are normally pressed upward by springs 29 insaid boxes (see dotted lines in Fig. 3) so that said bar 27 will. lock the stop or stops in position in the bar 2.5 by enga ement with the shoulder of the stop. The Took-bar 27 may be depressed however to uncover the lower ends of the. slots to permit the Withdrawal or insertion of a stop 26- in the proper place to suit the work to be tabulated.

The variable stop which travels with the carriage comprises a sleeve or barrel- 3O splined on a shaft 31 behind bar 35. shaft 31 is mounted in suitable bearings in the frame of the machine but having no endwisc movement relatively to said frame, said shaft having a pinion 32 engaged by a toothed segment 33 carried by an arm 34secured to a rock-shaft 35 mounted in bearings 36 'on frame ill (see Fig. 3).. Said sleeve or barrel 30 is provided with a spiral flange 37 which is )rei'erabl althou h not necessarilv ste )ed as shown, so as to abut against a stop 26 (see Fig. 8). I The sleeve also formed with.

a circumferential groove 38 which receives a blo -k or lug 39 [)I'OJGCtlIlg from the carriage and traveling therewith. It-will now be seen that the sleeve 30 and its spiral flange 37 constitutes a revolving and sl1d1ng'var1- able stop, since it slides on the shaft 31 when the carriage travels, and revolves with the shaft-31 when the latter is actuated by the rack 33. Ami since the said stop and carriage travel in unison, the carriage will be stoppedwhen a portion of idle spiral flange 37 strikes a stop 26, and the particular scale point at which the carriage will stop will be determined by the amount of rotation that has-been imparted to the shaft 31 and splined sleeve, through the medium of the rockshaft 35 and rack 33.

Two embodiments of meansfor actuating the rock-shaft are illustrated and will be path between the ends theflangewhichpresently described butbefore referring to.

either, it is essential that it be understood that the variable stop is'capable of freely passing the stop or stops.26 whenever the -machine is being usedin the ordinary man'- ner. As best shownin Figs. 8, 9 and 10, the flange 37 does not extend entirely around the sleeve and there is thus provided a space or will permit the variable stop; to pass a fixed stop 26 when the former isin its normal posr- Said tion which is that shown in Figs. 7 and 9 In order to'hol'cl the variable stop and the shaft 31 in this normal position, a s ring 40 is connected to the arrn.34 and the 'rame' of the machine (see Fig. '1) so as to normally hold said arm against a suitable stop which may be a portion of theframe of the machine indicated at 41 in Fig. 2. Therefore when the arm 34 is in the position shown in Fig. 1

the rack 33- and pinion 32 hold the shaft 31 7 5 and sleeve 30 in such position that the latter will occupy the position shown in Figs. 7 and 9. But when the rock-shaft has been actuated by means such as presently described, so that the arm 34 is thrown out of .normal position as indicated in Fig. .2, then the shaft 31 and the variable stop will be turned as indicated in Figs. Sand 10 sothat bearings 43 under the frame of the machine and hstvingjinger pieces or keys 44 which will be suitably marked to'indicat-e units, tens, hundreds, etc. Each rod 42 also has a collar 45 adapted to engage the lower edge of a swinging gate or bar 46 pivoted at 47 to the frame of the machine and -having'an arm 48 at an angle thereto. Practically, the bar 46 and its arm 48 constitutes a bell-crank lever adapted to be'actuated by any of the'push rods. The arm 48 is connected by a link 49 to a pin' projecting from the feed-dog 24 so that whenever a rod 42 is pushed into its farthest limit, its collar 45v actuates the bell-.- crank lever so as to pull down the dog 24 fromthe feed-rack 23 and thus release the carriage to permit the latter to be rapidly propelled by its spring in the manner usual with jump-feed devices. But before thepush rod reaches its innermost position so as to release the carriage as mentioned, the rock-shaft 35 is actuated, by means which I shall now describe, to bring the variable stop out of itsnormal inoperative position. To this end, each rod 42 is pivotally connected to a lever 501nounted to oscillate on a fulcrum rod 51 extending across'the back of the frame. 'Secured to and depending from the rock-shaft 35 are as many arms 52 as there are levers 50 and rods'42. The upper arm of each lever 50 is provided with a plate having a hook 53, said plate being secured to its lever by a bolt 54' or other equivalent f'asten ing passing throu h a slot in the lever whereby the position of the hoo'k'inay be adjusted toward or from the fulcrum of the lever.

Each arm 52' has a slot in which a pin 551's ment provided for the. hook 53 on its lever.

pair.

The pin 55 extends past the edge of the adj acent lever so as to be engaged by the latter when rod 42 is pushed in, thereby causing the parts to move irom the position shown in Fig. l to that shown in Fig. 2, the variable stop being thus rotated to an amount corresponding to which arm 52 is actuated and the point at which the pin is set along its arm. As shown in Fig. 3, the location of the pins 55 01 the ditlerent arms 52 vary. This is to vary the amount of movement that will he imparted to the rock-shaft and the variable stop.by the di'tl'erent push-rods.

As shown in Fig. 2, the hook 53 engages the pin. 55 in such inanner as to lock the key or push-rod and the rock-shaft at the end of the stroke to limit the movements of all the parts and also prevent over-throw of the rock-shalt and the variable stop due to n1omerit-um.

The construction described enables any one of the tabulating key rods to be actuated without aii'ectingthe others, owing to the fact that there is no pern'ia-nent connection between the levers 50 and arms 52 of each While all of the arms 52 will oscillate with the rock-shaft only one lever 50 will be moved. And when one lever 50 is in the position shown in Fig. 2 no other lever 50 can be operated so as to atl'ect the variable stop because the hook 53 of the actuated lever looks the rock-shaft by engaging the pin 55 of the actuated arm52.

In Figs. 5 and 6 the lovers which actuate the arms 52 are arranged to be operated by a downward instead of an inward finger movement. In said figures-where the parts are for the same purpose as similar parts in the other figures. I employ the same numerals with the addition of a cipher. In saidv figures, the arms 520 are longer than the arms '"2 in the other form, and extend inward from the rock-shaft 35 instead of downward, and are provided with pins 550. The levers 500 are mounted on lulcrum rod 510 extending under the machine, and at their inner ends carry the plates having hooks 530, said plates being adjustabiy secured by bolts 540 )assing through the slots of the lover. The books 530and pins 550 are adjustable along their slotted lovers in the same manner and for the same purpose described in connection with hooks and. pins 55. The outer ends of the levers 500 are'provided with vertical push-pieces +20 extending upward through a guide plate 430 and having linger pieces or keys 440. Mounted on the rod 510 is a rcc- ,tangular lever-i ra me 56 having its front bar extending under the front portions of all the lovers 500 and having, a link 4190 connecting its rear bar with one end of a short lever 57 pivoted at 58 to a suitable iiXe-d part or projection ofthe frame of, the machine. other end of the short lever 57 has a pin 59 adapted to contact with a pin 60 projecting The from the feed-dog 24. In this form the connections are such that upon the depression of a key 440, the rock-shaft 35 is first actuated to vary the position of the variable stop, which will be the same as in the other form first described, and then the lever frame will be actuated to lift the link 490 and cause the pin 59 of lever 57 to disengage the feed-dog 24 from the rack 23 and permit the carriage to jump as far as permitted by the stops which are supposed to be as shown in Figs. 7 to. 10.

by the edge of the lever 50 so thatthe former will be actuated by the latter. The dotted lines in Fig. 1]. represent these parts when they have been moved to the locked position hereinbetore described.

Since the portions of the several parts of the mechanism have been described in conncction with the descriptions of the parts themselves, a summary or complete description of the mechanism as a whole will not be necessary.
